So I'm working on my NS, and I'm faced with two options for the Concordat's history.

1) Make my own garden nation and species for them to be an offshoot of. If I did this, I'd probably make it so that the original species is now extinct, wiped out by the Concordat, because I don't want two nations.

2) Make the Concordat an offshoot of someone else's garden species/nation.

I'm really interested in doing #2. Shoot me a PM if you'd like to collaborate on this. Who wants a violent cyborg revolution in their history? :D
